HEADLIGHT.

V Applicatlonflled April 23, 1928. v Serial Ito. 684,601.

Be it known that I, Moses J. DAVIS, a citizen of the Unlted States,residing at Pueblo,

in the county of Pueblo and State of Colo-- rado,'have invented a newand useful Headlight, of which the following is a specificar tlon.

This invention relates to headlights of that type used for example onlocomotives.

One of the objects of the invention. isto provide means whereby, throughthe actuation of a switch, the lamp can be caused to throw either awhite light or a colored light.

Another object is to provide a headlight utilizing lamps of the colorsto be projected,

said lamps being stationary in the housing and so located that neitherof them will interfere with the proper projection of light rays from.the other.

A still further object is to provide improved means for mounting thelamps adjustably whereby they can be positioned ac- 33 Figure 2.

curately with reference to the reflector in the lamp housing.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combination of parts which" will be hereinafter morefully described and pointed out in the claim, it being understood thatvarious changes may be made in the construction and arrangement of theparts without departing from the spirit of the invention as claimed. Inthe accompanying drawings the preferred form of the invention has beenshown.

In said drawings: Figure 1 is a side elevation of the headlight.

Figure '2 is a front elevation thereof.

Figure 3 IS an enlarged section on-line Figure 4 is a rear elevation ofthe lamp support and reflector removed from the housing.

Figure 5 isa diagram of wiring that may be used with the lamps.

Referring to the figures by characters of reference 1 designates a lamphousing provided with the usual lens 2 at the front thereof and a door 3serves dicated at 4, is formed with a transverse 3. 4 The side walls ofthis channel are under- 7 I to close one side of the housing. The baseof the housing, in-

7 formed along opposite sides of a slide 8 insertable into the channel 5through the side f the housing. Secured on the slide 8 are standards 9soldered or otherwise attached to the rear portion of arefiector 10. p

The front portion of the reflector has an ear 11 extending tached to theslide 8.

10 is a pedestal 12 having a tubularbody portio 13 in which is slidablymounted a rotata 1e stem 14. This stem projects downwardlv from anangular-sleeve 15 inwhich downwardly therefrom at-. v

i Secured on the slide 8 back of the reflector is slidably mounted asupporting bar 16. 5 A set screw 17 serves to hold stem 14: against fmovement in the body 13 and another set screw 18 is used for holding thebar 16 against movement within the sleeve 15.

An opening 19 is provided in the rear end or apex portion of thereflector 10 and bar 16 extends throughthis opening. An incandescentlamp 20 is carried by the front end portion of bar 16 and is adapted tothrow a white light. Another incandescent lamp 21 is carried by bar 16directly back of lamp 20 and is designed to throw a red light. Bothlamps are electrically connected to a switch 2 that can be located inthe cab of the l0C( .otive or at any other convenient place. The lampscan be disposed in any suitable circuit such as shown for example inFigure 5.

It is to be understood that the bar 16 die be adjusted vertically andangularly relative to the reflector by loosening the set screw 17 andsliding and'rotating By loosening setscrew 18 bar 16 can be adjustedlongitudinally. Thus the lamps 20 and 21. can be properly positionedrelative to the reflector.

By moving the switch 22 to one position be placed in circuit and the Ithe lamp 20 will rays therefrom will be properly reflected by stem 14.

the reflector 10. As the lamp 21 is lpcatedf between lamp 20 and theopening 19 1t will lamp21 will be placed in cirm the red their properprojection will not he iutvrfered with.

By proi 'iding t. headlight such' as de scribed the usual White lightprojected therefrom can be quickly changed to a red light in the event01" an emergency or Whenever it is desired to display a danger signal.

While this invention is: designed especially for use on locomotives it1s to he understood that it can be employed efficiently on boats orwherever :1 head-light 13 used. 7 hat is ('lflllllOd is:

Ina headlight, the combination with a housing and a relieetor thereinhav ng an OPG IIi DQLlH the apex ortion thereof, ofav pedestal mountedin jtie housing and back of i he n icetor, a stein rotatably andslidably mountwi iii the pedestal, means for holding Witnesses dir allythrough the opening in the reflector,

and into position in front of the reflecting surface, front and rearlamps mounted en the ear and movable therewith into position in front ofthe opening in the reflector, and

means for closing a, circuit to either lump.

In testimony that I claim the foregoing as my own, I have hereto affixedby signature in the presence of two WiiLEiBSSGS.
